I didn’t have to change anything including secure boot when I removed windows and installed Fedora on my laptop. Should generally work, but there’s a possibility some newer features may not or may have a Windows-only setting and an other OS setting. Update the BIOS to the latest and just try it…
Don’t format, just create separate subvolumes for the distros and keep the home subvolume mounted on each root then delete the root subvolume of the distros you don’t want when you’re done with them.
